To (LIZ whom. 7115 may concern.:

Be it known that I, WILLIAM H. SHIERsoN, a citizen of the United States,residing at Adrian, in the county of Lenawee, State of Michigan, have invented certain new and useful Improvements in Dies for Tying Intersecting Wires; and Ido declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

rIhis invention relates. to dies for tying intersecting wires; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to provide suitable dies between which the cross-wires are confined and which are so shaped at their point of crossing as to enable a tie-wire in the form of a staple to be driven around said wires in a manner to form a knot or tie by means of which the wires are firmly united.

The above object is attained by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figures l and 2 are perspective views of the working faces of the dies between which the cross-wires arel tied. Fig. 3 is a transverse section through the dies closed upon the crosswires and between which the staple or tie has been driven to unite said wires as on line 3 3 of Fig. 5. Fig'. 4 is a similar view as on line 4 4 of Fig. 5. Fig. 5 is alongitudinal section through the dies embracing the-tie and cross wires as on line 5 5 of Fig 4. Figs. 6 and 7 are plan views of the dies shown in Figs. I and 2. Fig. 8 is a perspective view of the tie which is formed between the dies to unite the cross-wires, showing said tie in position upon said wires.

Referring to the characters of reference, l designates one of the dies, in whose working face is formed a depression 2,which is crossed longitudinally by the channel 3, adapted to receive the longitudinal wire 4, said channel 3 after crossing said depression extending outwardly across the face of the die to the end thereof. Leading from one end of the depression 2 are the curved tapering branches 5 and 6, which converge and terminate upon opposite sides of the channel 3. Formed transversely of the die, in the face thereof, is the cross channel 7, which crosses the curved branches 5 and 6 above the plane of the bottom thereof and cuts across the raised central portion 8 between said branches at right angles to the channel 3.

In the working face of the die 9 is an inclined way l0, adapted to permit of the introduction of the tying-staple and the following plunger, which forces-said staple around the cross-wires between the dies. Also formed in the working' face of said die isa transverse channel ll, which is adapted to register with channel 7 in the die l, and the short longitudinal channel 12, which leads from the inclined way l0 across the channel l1, terminating at the first oblong concavity 13, which is formed in the face of the die on the opposite side of channel ll from the Way 10. Also formed in the face of the die adjacent the concavity 13 is the oblong concavity 14, which stands obliquely to concavity 13 and occupies a position between the concavity 13 and the end of said die.

The depth of the longitudinal channel 3 is suficient to receive the entire diameter of the wire 4 except at the center, where said channel is suficiently shallow to force said wire into the short channel 12 when the dies are placed together, thereby forming the crimp l5 in said wires, (shown-in Fig. 8,) while the channels 7 and 11 are each of sufficient depth to receive one-half of the diameter of the crosswire 16 except at the junction'of said channels with the channels 3 and l2, where the channel 7 is depressed sufciently to allow the wire 4, which crosses wire 16, to force said last-named Wire into said depressed portion of channel 7 and crimp the wire, as shown at 17.

When the dies are brought together upon the cross-wires, said wires are received in the registering channels in the faces thereof, and the parts are so positioned as'to cause the terminal of the curved branch 6 toregisterwith one end of the oblongconcavity-13, While the terminal of the curved branch 5 registers with roo the opposite end of the oblong concavity 14. Because of this arrangement of the parts when the staple 18, which forms the tie, is driven into the dies through the inclined way 10 the legs of the staple enter the curved branches 5 and 6 of the depression 2 under the cross-wire 16, the leg 19 of the staple entering the branch 6 and being deected thereby laterally into the curved concavity 13, which directs said leg in a hooked form across the longitudinal wire, as shown at 2O in Fig. 8, the terminal of the hooked end of the leg entering a small recess 21 in die 1 between the curved branch 5 and channel 3, which allows said end to more perfectly hook over the wire 4. At the same time the leg 22 of the staple which enters the curved branch 5 is directed into the oblique concavity 14, which shapes the course of the end of said leg across the wire 4 and outwardly in a direction opposite to that of the hooked terminal of the leg 19, forming also at the end of the leg 22 a hooked portion 23, which engages over the wire 4, also shown in Fig. 8, there being in the face of the die 1 at the side of the channel 3 a recess 24 to receive the end of said hooked portion 23. In this manner the cross-wires are iirml y united by the staple,which is tied thereto, as shown in Fig. 8, in a manner to prevent the separation of said wires or the slipping of the wires upon each other. The dies by suitable means (not shown) are brought together upon the cross-wires and firmly held while the staple is being driven, and then separated to allow the united wires to pass therefrom.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Dies for tying intersecting' Wires, one of which is provided in the face thereofl with a depression and wire-receiving channels crossing at right angles, one of which extends longitudinally of said depression, there being curved branches leading from said depression crossed by the transverse channel and below the plane of said channel, the other die having longitudinal and transverse channels registering with the longitudinal and transverse channels of the first-mentioned die, there being in the face of the latter die two oblong concavities one of which stands transversely thereof, and the other of which stands obliquely to the first and occupies a position between said first-mentioned concavity and the end of the die, said oblong concavities being adapted when the dies are placed together, to register respectively With the curved branches of the die first mentioned.

2. Dies for tying intersecting wires, one of which is provided in the face thereof with wire receiving channels crossing at right angles which extend longitudinally and transversely of the face of the die, there being in the face of the die a central depression which is crossed by the longitudinal channel and from which lead curved branches which cross the transverse channel below the plane thereof, the other die having an inclined way in the face thereof and wire-receiving channels crossing at right angles, adapted to register with the wire-receiving channels in the first-mentioned die, there being in the face of the second die two oblong concavities, one of which is connected by the longitudinal channel with said inclined Way, and the other of which stands obliquely to the first and is disposed between the first-mentioned concavity and the end of the die.

3. Dies for tying intersecting wires, both having channels in their faces crossing at right angles, one also having a depression and two curved branches leading therefrom across one channel and two recesses adjacent the other channel and in line with Said branches, and the other die having two oblong concavities each adapted to span the space between one of said branches and its coperating recess.

In testimony whereof I sign this specification in the presence of two witnesses.

WILLIAM H. SHIERSON.
